Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · VSSOP-8-0.65mm
LP2989IMM-5.0 from Texas Instruments, in a VSSOP-8-0.65mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BYPASS | input | Bypass capacitor input; connecting an external 10-nF capacitor here reduces output noise to 18 µV (typical). |
| 2 | N/C | unconnected | Do not connect; reserved for post-packaging test and calibration, must be left floating and not connected to any potential. |
| 3 | GROUND | power_in | Ground pin for the regulator. |
| 4 | INPUT | input | Regulator power input; the device is designed for an input supply range of 2.1 V to 16 V. |
| 5 | OUTPUT | output | Regulated output voltage; the absolute maximum survival output voltage is -0.3 V to 16 V. |
| 6 | SENSE | input | Feedback voltage sense input; the SENSE pin absolute maximum rating is -0.3 V to 6 V. |
| 7 | ERROR | output | Error signal output that goes low when the output drops approximately 5% below nominal. |
| 8 | SHUTDOWN | input | Shutdown input; the device draws less than 0.8 µA quiescent current when this pin is pulled low, and it must be actively terminated (tie to IN, pin 4, if not used). |
